“Listen now,” said Jadwin. He took a perforated roll from the case near at hand and adjusted it, Gretry looking on with the solemn interest that all American business men have in mechanical inventions. Jadwin sat down before it, pulled out a stop or two, and placed his feet on the pedals. A vast preliminary roaring breath soughed through the pipes, with a vibratory rush of power. Then there came a canorous snarl of bass, and then, abruptly, with resistless charm, and with full-bodied, satisfying amplitude of volume the opening movement of the overture of Carmen .

“Great, great!” shouted Gretry, his voice raised to make himself heard. “That’s immense.”

The great-lunged harmony was filling the entire gallery, clear cut, each note clearly, sharply treated with a precision that, if mechanical, was yet effective. Jadwin, his eyes now on the stops, now on the sliding strip of paper, played on. Through the sonorous clamour of the pipes Gretry could hear him speaking, but he caught only a word or two.
